I need a GOOD stock carb for my GX160. I've been through this one and it just won't idle. Takes gas fine, but starts hard and wont idle. I've tried the fuel pump, gravity feed, limiting the fuel pump and nothing. If you have one that you know is good(as is you saw it run/idle), let me know. I'd go aftermarket, but this is a low buck rider and I'm done spending money at this point. If I buy a Mikuni, I'll buy a cam springs and so on...:doah:
